Abstract

In this study we analyzed the NmF2 data by wavelet analysis at the time of strong seismic event. We used Ionosonde data for analysis. Data of maximum electron density of F2 layer (NmF2) was collected from NOAA space environment center. With the help of Mat-Lab software wavelet analysis performed. Results of the study showed some unusual perturbations in NmF2 parameter few days before earthquake. This fact can be used as precursory phenomena. It may be due to the emission of energy from the earth rock which propagate upward and perturb the F-region of ionosphere. This study may be useful for earthquake prediction.
